Answer 1

Step-by-step explanation:

For CaO (calcium oxide), the properties that you would expect are:

1. It is not likely to be a gas or liquid at room temperature. CaO is a solid compound.

2. It is likely soluble in water. Calcium oxide reacts with water to form calcium hydroxide, which is soluble in water.

3. It will not likely light up a bulb in a conductivity apparatus. CaO is not a conductor of electricity in its solid form.

4. It will likely have a high melting point. Calcium oxide has a melting point of around 2,572 degrees Celsius, which is relatively high.

So, the correct properties for CaO are:

- It is likely soluble in water.

- It will likely have a high melting point.
